Tile unit

ABSTRACT

Disclosed is a tile unit (10) that includes a resin net (20), a plurality of tiles (30) disposed on a front side of the resin net, and a magnet sheet (40) disposed on a back side of the resin net, with the tiles being bonded and fixed to the magnet sheet with the resin net interposed therebetween.

FIELD OF THE INVENTION

The present invention relates to tile units that allow a plurality oftiles to be mounted onto a wall surface or the like as a unit.

BACKGROUND OF THE INVENTION

A technique for mounting a tile or tiles onto a wall surface or the likewith a magnet or magnets is known, as disclosed in Japanese PatentApplication Laid-Open Publication No. 09-111997, for example.

The tile disclosed in Japanese Patent Application Laid-Open PublicationNo. 09-111997 is composed of a molded body, which is formed from a thinmetal plate, and a magnetic body mounted on the back surface of themolded body. The magnetic body enables the tile to be attached to aniron plate. Therefore, it is possible to mount and remove the tile. Inaddition, the molded body of a thin metal plate provides a solid-lookingtile surface.

Japanese Patent Application Laid-Open Publication No. 09-111997 issilent as to the intended use of the tile. It is speculated that thetile may be used for a nameplate with a company name inscribed thereonor for a doorplate at a residence, for example. When the tile is usedfor such purposes, the lengthwise (or widthwise) dimension of the tileis typically from 50 mm to 500 mm.

Among tiles, there is a mosaic tile. Mosaic tiles are tile units thatprovide a sophisticated design appearance as a large number of tilepieces, each measuring several millimeters to several tens ofmillimeters, are arranged.

When the technique disclosed in Japanese Patent Application Laid-OpenPublication No. 09-111997 is applied to a mosaic tile, the followingproblem arises.

In order to mount a magnetic body to each of the tile pieces of themosaic tiles, the magnetic body needs to be prepared in a number equalto the number of the tile pieces. This increases the number of times themagnetic bodies are mounted, and in turn increases the mounting cost.Furthermore, each magnetic body has small dimensions, and therefore itis troublesome to mount the magnetic bodies. This further increases themounting cost. Consequently, the mosaic tiles become expensive.

Expensive mosaic tiles find limited usage and demand.

In consideration of promoting the widespread use of mosaic tiles, thereis room for improvements.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a tile unit that allowsa plurality of tiles to be mounted onto a wall surface or the like as aunit and that is less expensive.

According to a first aspect of the present invention, there is provideda tile unit that includes a resin net, a plurality of tiles disposed ona front side of the resin net, and a magnet sheet disposed on a backside of the resin net.

In the tile unit, the tiles are bonded and fixed to the magnet sheetwith the resin net interposed therebetween.

In the present invention, a plurality of tiles are bonded and fixed tothe magnet sheet with the resin net interposed therebetween. Thethickness of an element (twisted yarn) in the resin net slightly variesdepending on the position. Therefore, the tiles become slightly tiltedrelative to the magnet sheet. Consequently, the tiles become slightlyragged, and the reflection off the front surface becomes irregular. Thisprovides an interesting design appearance.

A plurality of tiles may be bonded and fixed in advance to the frontsurface side of a single resin net, and then a single magnet sheet maybe bonded to the back side of the resin net.

In other words, a plurality of tiles can be bonded and fixed to thesingle magnet sheet with the resin net interposed therebetween. Ascompared to a case in which a single magnet sheet is bonded and fixed toa single tile, the present invention can reduce the cost for mounting amagnet sheet, and a less expensive tile unit is provided. Providing atile unit having a sophisticated design appearance inexpensively canpromote the widespread use of the tile unit.

Preferably, a jointing space is provided (left) between one of the tilesand an adjacent one of the tiles. Each of the tiles preferably has atrapezoidal shape in a cross-sectional view, and a back surface of eachtile, which comes into contact with the resin net, has a smaller areathan a front surface thereof.

A side surface between the back surface and the front surface is tilted,and outside light is less likely to hit the lateral surface. Therefore,the sophisticated design appearance on the front surface of the tiles isnot spoiled.

Preferably, each of the tiles is made of any one of glass, natural rock,ceramics, wood, and painted resin.

Glass, natural rock, ceramics, wood, and painted resin all provideglossiness, and a sense of luxuriousness.

Preferably, the natural rock includes crushed rock obtained by crushingnatural rock, a pebble that is a type of natural rock, and an adhesiveresin that bonds the crushed rock to the pebble.

The crushed rock and the pebble provide various reflection surfaces, andtherefore an optically interesting phenomenon can be expected.

According to a second aspect of the present invention, there is provideda tile unit that includes a resin net, a plurality of tiles disposed ona front side of the resin net, and a case disposed on a back side of theresin net.

In the tile unit, the tiles are bonded and fixed to the resin net.

The tiles bonded and fixed to the resin net is housed in the case. Thethickness of an element (twisted yarn) in the resin net slightly variesdepending on the position. Therefore, the tiles tilt slightly.Consequently, the tiles become slightly ragged, and the reflection offthe front surface becomes irregular. This provides an interesting designappearance.

A plurality of tiles are bonded and fixed in advance to the front sideof a single resin net, and this is housed in a single case.

Because the tiles can be housed in the single case as a unit, a lessexpensive tile unit is provided. Providing a tile unit having asophisticated design appearance inexpensively can promote the widespreaduse of the tile unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a configuration of a tile unit 10 according to anembodiment of the present invention will be described.

The tile unit 10 includes a resin net 20 illustrated in the center ofFIG. 1, a plurality of (in this example, 8×8=64) tiles 30 disposed on afront side of the resin net 20, and a magnet sheet 40 disposed on a backside of the resin net 20.

The magnet sheet 40 is a rectangular sheet having a thickness of 0.4 mmto 3.0 mm, a widthwise dimension of “A,” and a lengthwise dimension of“B.” Preferably, the side of the magnetic sheet 40 that comes intocontact with the resin net 20 is white or silver. The side of the magnetsheet 40 that faces a wall surface (the reference numeral 50 in FIG. 4)can be in any color, e.g., black or brown.

“A” is selected from a range of 50 mm to 1000 mm, and “B” is alsoselected from a range of 50 mm to 1000 mm. “A” and “B” are basicallyequal to each other, but they may be different from each other.

The resin net 20 is made, for example, of a twisted yarn 21 obtained bytwisting a small-diameter resin filament. The twisted yarn 21 has adiameter of 0.5 mm to 1.0 mm.

The resin net 20 is preferably a lattice net in which the twisted yarn21 is disposed in the lengthwise and widthwise directions. It issatisfactory as long as the mesh size be smaller than the lengthwise (orwidthwise) dimension of each tile 30, and the mesh size is, for example,5 mm.

The resin net 20 is preferably white. When the resin net 20 has the samecolor as the magnet sheet 40, the resin net 20 is less noticeable on afront surface 41 of the magnet sheet 40.

The resin net 20 can be modified to a net made of a natural twisted yarnor a net made of a paper twine, but a natural twisted yarn or a papertwine rots upon absorbing water. In this respect, a resin filament doesnot experience rotting upon absorbing water.

Referring to FIGS. 2A to 2C, the tile 30 will be described in detail.

As illustrated in FIG. 2A, the tile 30 is preferably a square plate. Itshould be noted, however, that the tile 30 may be rectangular, circular,elliptical, oval, or rhomboid. Each of the sides of the tile 30 may haveany value in a range of 3 mm to 300 mm, and 5 mm, 10 mm, or 20 mm isrecommended.

The tile 30 may be made of any one of glass, natural rock, ceramics,resin, imitation rock, wood, paper, metal, or a combination thereof. Forexample, a resin substrate may be coated with a paint in which metalpieces are mixed. Alternatively, the tile 30 may be a mud-based tileformed by solidifying volcanic ash, sand, or mud.

Among the above, glass, natural rock, ceramics, wood, and painted resinexcel in glossiness and are desirable. Among glass, natural rock,ceramics, wood, and painted resin, glass can be molded with ease and isdesirable.

When the tile 30 is made of glass, a pattern such as a stripe pattern(including a wave pattern) 32 can be formed in a front surface 31 withease within a process of glasswork.

The tile 30 may be a right-triangular plate. This is because non-squaretiles 30 are useful when a picture is expressed with the tiles 30 in theform of a mosaic image.

FIG. 2B is a sectional view taken along the b-b line in FIG. 2A. Thetile 30 preferably has a thickness of approximately 3.5 mm and has atrapezoidal shape in a cross-sectional view. Furthermore, a back surface33, which comes into contact with the resin net 20, of the tile 30preferably has a smaller area than the front surface 31.

One of the reasons therefor will be described with reference to FIG. 2C.

As illustrated in FIG. 2C, when a jointing space 34 is provided (orleft) between one tile 30 and an adjacent tile 30, outside light 35passes through the jointing space 34 and hits a lateral surface 36 ofthe tile 30. When the lateral surface 36 shines upon being hit by theoutside light 35, the sophisticated design appearance of the frontsurface 31 is spoiled.

As a countermeasure, the tile 30 is formed to have a trapezoidal shapein a cross-sectional view, and the back surface 33 is made to have asmaller area than the front surface 31. As a result, the lateral surface36 becomes tilted, and the outside light 35 does not hit the lateralsurface 36. Even if the outside light 35 hits the lateral surface 36,reflection light does not travel to the outside. Consequently, thelateral surface 36 does not shine upon being hit by the outside light35. Therefore, the front surface 31 of the tile 30 can serve as asophisticatedly designed surface.

It should be noted that filling (charging) the jointing space 34 with awhite or transparent jointing material does not pose any problem. Inthis embodiment, however, the jointing space 34 is not filled withanything. Filling the jointing space 34 with nothing enhances astereoscopic effect of each tile 30. On the other hand, filling thejointing space 34 with a jointing material prevents the jointing space34 from being clogged with dir. This facilitates cleaning. Therefore,whether to fill the jointing space 34 with a jointing material or notcan be determined as desired.

Referring to FIGS. 3A to 3C, the resin net 20 will be described indetail.

As illustrated in FIG. 3A, the resin net 20 is preferably a lattice net.It should be noted, however, that the resin net 20 may be a hexagonalnet or a rhombus net.

FIG. 3B is a cross-sectional view taken along the b-b line in FIG. 3A.The diameter (thickness) of the twisted yarn 21 is not uniform. Inaddition, the twisted yarn 21 flattens upon receiving an external force.

As shown in FIG. 3C, the tiles 30 and 30 are bonded and fixed to thefront surface of the resin net 20, and the magnet sheet 40 is bonded andfixed to the back surface of the resin net 20. In this case, the resinnet 20 is compressed in a nonuniform manner. Then, one of the tiles 30is mounted onto the magnet sheet 40 with the front surface 31 of thetile 30 being tilted by an angle θ1 relative to the front surface 41 ofthe magnet sheet 40. In addition, the other one of the tiles 30 ismounted onto the magnet sheet 40 with the front surface 31 of the tilebeing tilted by an angle θ2 relative to the front surface 41 of themagnet sheet 40. The angle θ1 and the angle θ2 inevitably differ fromeach other. A difference in the angle of reflection is produced betweenthe two front surfaces 31, and a stereoscopic effect is created as awhole. This enhances design sophistication.

In FIG. 3C, an adhesive plays a role of bonding and fixing the magnetsheet 40 onto the back surface of the resin net 20. In addition, acertain part of the adhesive plays a role of directly bonding and fixingthe tiles 30 onto the magnet sheet 40. In other words, this embodimentof the present invention provides the tile unit 10 having a structure inwhich the tiles 30 are bonded and fixed to the magnet sheet 40 with theresin net 20 interposed therebetween.

The twisted yarn 21 is highly elastic. If an external object hits thefront surface 31 of the tile 30 in FIG. 3C, the resin net 20 absorbs theimpact. Consequently, the tile 30 is less likely to break or be damagedupon an object making contact with the tile 30.

Therefore, the tile unit 10 as illustrated in FIG. 4 is obtained.Specifically, the tile unit 10 has the tiles 30 such that the tiles 30are bonded and fixed to the magnet sheet 40 with the resin net 20interposed therebetween.

A procedure for mounting the tile unit 10 having the above-describedstructure to a wall surface 50 will now be described.

As illustrated in FIG. 4, preferably, the wall surface 50 is coated witha magnetic paint to form a magnetic paint layer 51. The magnetic paintis a paint that contains a suitable amount of iron powder particulates.By coating the wall surface 50 with the magnetic paint a plurality oftimes, the magnetic paint layer 51 with a predetermined (or desired)thickness can be formed. Alternatively, the magnetic paint layer 51 maybe a thin plate made of an iron-based material.

As the magnet sheet 40 is magnetically attached to the magnetic paintlayer 51, the tile unit 10 is mounted onto the wall surface 50.

When the tiles are made of glass, ceramics, or natural rock, the tileunit 10 is heavy. However, the magnet sheet 40 produces a gripping forceof several tens times more than the own weight of the tile unit 10, andtherefore the tile unit 10 does not fall. Even if the tile unit 10 movesdue to a large earthquake or the like, the tile unit 10 can be put backin place with ease.

The affixing operation can be performed by a general service person oran ordinary person other than a tiling professional.

When tiles are affixed to the wall surface 50 with mortar or an adhesiveas in a conventional construction method, a curing period is requireduntil the strength of the mortar or the adhesive is ensured. Theembodiment of the present invention, however, renders such a curingperiod unnecessary.

Therefore, the time and the cost required for the affixing can bereduced to a great extent.

A construction example of the tile unit 10 will be described withreference to FIG. 5.

As illustrated in FIG. 5, the tile units 10 are affixed to lateral wallsof a marble counter 53. The tile units 10 of the embodiment of thepresent invention can be replaced even by an ordinary person, andtherefore the tile units 10 may be replaced with tile units of differentcolors and/or patterns for each season, for example.

Referring to FIGS. 6A to 6C, modifications will now be described.

As illustrated in FIG. 6A, the tile unit 10 includes the resin net 20,the tiles 30 disposed on the front side of the resin net 20, and a case60 disposed on the back side of the resin net 20. The case 60 is made ofresin or metal, and includes an edge 61 that is integrally formed withthe case 60 and that projects inward from an opening edge of the case.

A unit in which the tiles 30 are bonded and fixed to the resin net 20 ishoused into the cylindrical case 60 having a bottom. At this point, theedge 61 is elastically spread to allow the aforementioned unit to behoused into the case 60. The edge 61 can prevent the tiles 30 and theresin net 20 from coming off the case 60.

When the case 60 is made of metal, the edge 61 may be bent after theaforementioned unit is housed into the case 60.

The obtained tile unit 10 can be used as a coaster. Specifically, thecoaster (tile unit 10) is placed on a table or a counter with the tiles30 facing upward, and a fancy wine glass is placed on the coaster (tileunit 10). A coaster suitable for a fancy wine glass is provided. Inaddition, the edge 61 can function as a frame, and therefore the tileunit 10 illustrated in FIG. 6A can be used as a wall-hanging piece ofart or as a piece of art in a photo frame.

As illustrated in FIG. 6B, the tile unit 10 includes the resin net 20,the tiles 30 disposed on the front side of the resin net 20, and thecase 60 disposed on the back side of the resin net 20.

A unit in which the tiles 30 are bonded and fixed to the resin net 20 ishoused into the cylindrical case 60 having a bottom. In this case, thetiles 30 are bonded and fixed to the bottom of the case 60 with theresin net 20 interposed therebetween. The tile unit 10 illustrated inFIG. 6B is suitable as a coaster.

As illustrated in FIG. 6C, the tile unit 10 includes the resin net 20,the tiles 30 disposed on the front side of the resin net 20, and asomewhat large case 60 disposed on the back side of the resin net 20.

A unit in which the tiles 30 are bonded and fixed to the resin net 20 ishoused into the somewhat large case 60, and a space between theaforementioned unit and the inner surface of a wall 62 of the case 60 isfilled with an edging material 63 of an appropriate color.

Because the edging material 63 can function as a frame, the tile unit 10illustrated in FIG. 6C is suitable as a wall-hanging piece of art or apiece of art in a photo frame. This tile unit 10 is also suitable as acoaster.

Each of the tile units 10 illustrated in FIGS. 6A to 6C includes theresin net 20. Therefore, the inclinations of the front surfaces ofadjacent tiles 30 differ slightly from each other. This enhances designsophistication. Because the resin net 20 acts as a cushion, the tiles 30are less likely to be damaged.

The tiles 30 are housed all together into the single case 60. Therefore,the tile unit 10 that is less expensive and that is easy to handle isprovided.

As illustrated in FIG. 1, the tile unit 10 of the embodiment of thepresent invention provides an appearance resembling an array of gems andprovides a sense of luxuriousness. Therefore, the tile unit 10 can befitted into a lateral wall of a counter in a high-class restaurant orinto a wall of a lobby in a high-class hotel or an art museum. Inaddition, the tile unit(s) 10 of the embodiment of the present inventioncan be fitted into the entirety or a part of a wall in a dressing room(a lavatory or a powder room).

Furthermore, the tile unit 10 can be constituted by tiles 30 made ofdifferent materials, having different colors, or having differentpatterns, and the tile unit 10 can be hung on a wall of the like in theform of a piece of art (work of art). Therefore, the use of the tileunit 10 is not limited.

In addition, the shape of the tile 30 may not be a trapezoidal shape ina cross-sectional view, e.g., the lateral surface 36 may extendorthogonal to the front surface 31. The shape of the tile 30 is notlimited. The dimensions and the materials of the tile 30 may bedetermined as desired and are not limited to those described in theembodiment and the modifications.

Although the assumption is that the tile unit 10 of the embodiment ofthe present invention is fitted onto the wall surface 50, the tile unit10 can also be fitted onto an upper surface of a table, a ceilingsurface, or a floor surface. Therefore, the tile unit 10 can be mountedonto any desired target.

The tile 30 illustrated in FIG. 2A may be obtained as follows.Specifically, crushed rock obtained by crushing natural rock may bemixed with pebbles that are a type of natural rock, and the mixture maythen be solidified with an adhesive resin into a panel shape. The tiles30 are slightly tilted by the resin net 20, and the crushed rock and thepebbles provide various reflection surfaces. Therefore, an opticallyinteresting phenomenon can be expected.
